Constraining the Lifetime of Quasars from Their Spatial Clustering
The lifetime of the luminous phase of quasars is constrained by current observations to be 10 ∼< tQ ∼< 10 years, but is otherwise unkown. We model the quasar luminosity function in detail in the optical and X–ray bands using the Press–Schechter formalism, and show that the expected clustering of quasars depends strongly on their assumed lifetime tQ. We quantify this dependence, and find that ex...
متن کاملLarge-scale distribution of quasars in deep pencil-beam surveys
We have used integral two-point spatial correlation function and its second derivative to analyze the distribution of quasars in three very deep surveys published in the literature. Statistically significant (∼ 2 − 3σ) correlations were found at scales of ∼ 50 − 100h Mpc in all of the analyzed surveys. We have used the friend-of-friend cluster analysis to show that these correlations can be exp...
متن کاملSpatial Distribution of Premature Infant Mortality in 2000-2017
Background The provision, maintenance and promotion of the health of infants as a vulnerable group in health care services are a high priority, and the first step in reducing infant mortality and improving their health is undoubtedly the identification of their mortality status. We aimed to study the spatial distribution of premature infant mortality in 194 count...
متن کاملBroad band energy distribution of ROSAT detected quasars
A database of radio-quiet quasars detected with ROSAT is presented containing 846 quasars seen in the All-Sky Survey and/or in pointed PSPC observations. About ∼ 70% of the objects have been detected in X-rays for the first time. We present the soft X-ray fluxes and spectra, if available. Using an optically selected subsample compiled from this database we study the broad band properties of rad...
متن کاملDust and the Ultraviolet Energy Distribution of Quasars
The ultraviolet energy distribution of quasars shows a sharp steepening of the continuum shortward of 1000 Å (rest-frame). We describe how we came to consider the possibility that this continuum break might be the result of absorption by carbon crystallite dust grains.
